Title: SD Server Directory Traversal Vulnerability
Severity: HIGH
Description:
SD Server is a freely available web server.
A vulnerability has been identified in the handling of certain types of requests by SD Server. Because of this, it is possible for an attacker to gain access to potentially sensitive system files.
The problem is in the handling of directory traversal strings. When a request containing directory traversal '../..' sequences is sent to a SD web server, the program allows a remote user to escape the web root directory. This issue could be exploited to gain read access to files on a host using the vulnerable software. Read privileges granted to these files would be restricted by the permissions of the web server process.
This vulnerability is reported to affect SD Server versions up to and including version 4.0.70.
Affected Products:
- GD Software SD Server 4.0.70
